Ha! Of COURSE they do! Didn't you know? We got OUR interests in prime numbers from aliens, and they are still interested, e.g., still trying to find an algorithm to factor integers that runs in O(n) for an integer of n decimal digits. Why decimal? I know the answer, but there is no room in this post for me to write it down!

And for 'The Book', Paul Erdős, that was from aliens, too. Why? Sure, could there be any doubt, Erdős was one of them!
